Hi,

My requirement is like the below.

do n times.

data : itab<n> type table of <>.

enddo.

Itab1 itab2 iab3 -

itabn are to be created based on the sy-index.

Any body have any idea how to achieve this.

Regards,

Surendar Reddy.

Check this sample code for logic

DATA :ITAB_NAM(6) TYPE C.

DATA :ITAB_NAME(40) TYPE C.

DATA:W_IND(2) TYPE C.

DO 5 TIMES.

W_IND = SY-INDEX.

CONCATENATE 'itab' W_IND INTO ITAB_NAM.

CONCATENATE 'DATA' ':' ITAB_NAM 'TYPE' 'STANDARD' 'TABLE' 'OF' INTO ITAB_NAME SEPARATED BY SPACE.

WRITE : ITAB_NAME.

ENDDO.

with regards

Well, what may be working is something like this


TYPES: BEGIN OF ts_tables,
         index LIKE sy-index,
         ref TYPE REF TO data,
       END OF ts_tables.

TYPES: ts_dynamic_table TYPE soli.
TYPES: tt_dynamic_table TYPE STANDARD TABLE OF ts_dynamic_table WITH DEFAULT KEY.

DATA: lt_tables TYPE HASHED TABLE OF ts_tables WITH UNIQUE KEY index.
DATA: ls_tables TYPE ts_tables.

DATA: ls_dynamic_table TYPE ts_dynamic_table.

FIELD-SYMBOLS: <table> TYPE ANY TABLE.
FIELD-SYMBOLS: <lt_tables> LIKE LINE OF lt_tables.

* Creating Tables
DO 5 TIMES.
  ls_tables-index = sy-index.
  CREATE DATA ls_tables-ref TYPE tt_dynamic_table.
  INSERT ls_tables INTO TABLE lt_tables.
ENDDO.

* Accessing Tables
DO 5 TIMES.
  READ TABLE lt_tables ASSIGNING <lt_tables> WITH TABLE KEY index = sy-index.

  IF ( sy-subrc = 0 ).
    ASSIGN <lt_tables>-ref->* TO <table>.

    ls_dynamic_table-line = sy-index.
    INSERT ls_dynamic_table INTO TABLE <table>.
  ENDIF.
ENDDO.

This example dynamically creates 5 internal tables of structure soli which are accessible by an index, and write a single line to each one of them.

REPORT abc.

CLASS l_table DEFINITION.
    PUBLIC SECTION.
    data : itab type standard table of mara.
  endclass.

 CLASS l_table IMPLEMENTATION.
   ENDCLASS.

   types : begin of ty_tables,
            index type  sy-tabix,
           lc_ref  type ref to l_table,
     end of ty_tables.


    START-OF-selection.
 data : i_tables type STANDARD TABLE OF ty_tables,
       wa_tables type ty_tables.
     do 3 times.
       wa_tables-index = sy-index.
       create object wa_tables-lc_ref.
       append wa_tables to i_tables.
       enddo.

this code will create internal table of type mara only..If you want dynamic internal tables , please search for dynamic internal tables and modify this code accordingly.

you have one internal table for each instance of the class as an attribute . access your internal tables as per your requirement
